"ValueError: need more than 5 values to unpack"

Hi,

This reminds me an old bug that I have already fixes. Can you confirm that you are working with the latest version of the code?

Cheers,

Olivier

Working with version 2.5.5.

Hope you could guide me !

I must say that I am running

t bp~ > w+

where bp~ is a new bottom partner heavier than the SM one. I assigned it the PDG number 8880013. Don't know if the latter might be the cause

Hi,

What are you trying to do?
We can not integrate such process since it is over constrain (3 degree of freedom associated to the w+ and 4 constaint from energy-momentum conservation). So it make perfect sense that the code crash in this case.

Cheers,

Olivier
